Based on the analysis of the power consumption constitution of the natural gas purification devices in low-load operation, this paper analyzed the cause of the increasing in electricity consumption and gas consumption, then discussed the energy conservation measures through modification in operation and transformation in technology. Practical adjustments included adjusting the layers of the solution putting into tower and circulation amount in the desulfurization unit, the fuel gas of the sulfur recover unit, the load and volume of the wind of stove boiler; and he running time of sewage unit according to the actual situation, as well as starting or stopping mobile device of water circulation unit. Technological aspects include using the excess air volume of the burning furnace fan, adding the side road of the DC sulfur recovery device, and transforming the solution circulating pump stages and low pressure steam loop of the sulfur intercooler. Through modification in operation and transformation in technology, the power consumption of he device in low-load operation was effectively reduced.
